Building Model for RFEM 6 | Features

If you are planning a building with several stories, the Building Model add-on is the perfect tool for you. It allows you to define stories for your building. You can also adjust the stories in many ways afterwards – exactly the way you need.

You can perform stiffening calculations, design shear walls, analyze floors as separate 2D structures, determine key parameters for dynamic analysis, and much more.

Floor Analysis as Detached 2D Structures

The building model calculation allows for a differentiated result display, depending on the story modeling. First, the entire model is created in 3D where the floors are modeled either as rigid planes or as a semi-rigid plane. Thus, it is possible to perform a design that is similar to positional structural analysis, but does not neglect the effects of the 3D model.

The results of both 3D and 2D calculations are combined into a single model, which facilitates data exchange and eliminates potential errors. Vertical surfaces can further be divided into shear walls and deep beams (lintels), from which the program automatically generates result members that can be designed directly in the design add-ons.
Building Story Generator

The building story generator provides you with the option to automatically create building stories, depending on the topology of the model.
Center of Rigidity

You can display the center of rigidity in tabular and graphical form. Use it for your dynamic analysis, for example.

Sensitivity Coefficient

When performing seismic analysis using the response spectrum of building models, the sensitivity coefficients for the horizontal directions of individual stories are displayed in a clearly arranged table.

This table provides a clear representation that helps you to understand how the model will react to various loads and actions, thus providing a valuable input to the quality of your analysis.

Intuitive Data Input

You have two options regarding the building model. You can either create it at the beginning of the structural modeling process or activate it afterwards. You can then use the building model to directly define and manipulate floors.

When manipulating floors, you can select from a variety of options to modify or retain the included objects.

Calculation of Center of Gravity Considering Loads

The center of gravity is displayed for load conditions and load combinations in the “Results by Story” table of Building Model. In addition to the self-weight, the vertical loads of the respective conditions are also taken into account.

You can also use the“Center of Gravity and Information on Selected Objects” dialog box to display the center of gravity in relation to specific selected loads. This facilitates the stability analysis and the optimization of the design.

It is also possible to graphically display the resulting center of mass and stiffness.
